NEW YORK, N. Y., A CQRPORATION OF DELAWARE REFRIGERAIOI? CABINETCONSTRUCTION Application filed July 27,

My invention relates to the art of refrigeration and particularly tothat phase of the.

1e suitably securing thereto a box-like metal liner having one openside. Suitable insulating material is placed around the five remainingsides of the liner and retained tightly in place by metallic hands. Thisassemm bly is then placed and suitably secured within an outer shellwhich is provided with a door for closing the open side of the liner.'Due to the reduction in the amount of materials and labor required sucha cabinet may be manufactured at a much lower cost than has heretoforebeen possible.

Furthermore my improved construction prevents condensation of moistureadjacent the liner. 89 cabinet is not tight against the liner and aircan getin between the insulation and the liner, moisture precipitatesdue. to the low temperature prevailing. This condensation must beguarded against, particularly with mechanical refrigerator units, bothto prevent water falling on the floor and to prevent rotting ofinsulation. ZBy impregnating and coating the insulation with a suitableWater proofing material of semi-viscous character and strapping theinsulation tightly around the liner, I am able tofprevent air pocketsnext'to the liner and avoid condensation of moisture.

My invention is fully pointed out inthefollowing description taken inconnection with the accompanying drawin s and further objects andadvantages will e apparent therein.

Fig. 6 is a top elevational view of the assembly shown in Figs. 4 and 5;

Fig. 7 is a view, partially in cross-section of some of the memberswhich constitute the interior assembly prior to being secured together.v

The interior assembly as shownin Figs. 4 through 7 will first bedescribed. The assembly, in its preferred form, comprises two uprightmembers 10 secured together by two horizontal. members 11 and 12.Members 10 and 11 and 12 are preferably of wood and constitute a framewhich lies in a single vertical plane Member 11 is connected to members10 at the top while member '12 is connected to them at a point somedistance above the bottom. i

Securely attached to this frame by means of screws 13 is a liner 14.Liner 14 is box-- shaped and has closed sides, top, bottom and back butan open front. The interior of the liner itself is preferably lined withporcelain fused thereonto Around the five closed sides of the liner isplaced a suitable heat nsulating material 15 such as cork boardimpregnated with water proofing fiuid material such as hydrolene. Thecork board may be in one. single layer as is shown in Figs. 3 and 7 ortwo or more layers may be employed. In case a plurality of layers areused, the transverse oints in adjacent layers should be staggered sothat there will be no joint extending all, the way through the in--'sulation at any one place.

' On the outsideof the insulating material may be placed one or morelayers of water proof paper (not shown). At the top, bottom and rearedges of insulation outside of the Water proof paper are placedprotective 1 onal view of the angle pieces 16. These angle pieces do notnecessarily extend the entire length oftheir respective edges. Two ormore metal bands 17 are secured to horizontal member 11, pass acrossthetop of the insulatedliner, down the back and underneath the bottomand are secured to lower horizontal member 12. A similar set of bands 18pass around the sides.

' and back of the insulated liner and have their frame. The pressure ofthe bands on the corner of the insulating material 15 is first appliedto the protective angle pieces 16 which distribute the pressure evenlyalong the respective edges.

An aperture is provided in the bottom of liner 14 and adjacentinsulation through which extends a short length of drain pipe 21. Anaperture may be cut in the back of the cabinet for the passage ofconduits for conducting refrigerant fluid to and from an evaporator.

Theparts and their relationship thus far described constitute the innerassembly which is placed within an outer shell 22; Shell 22 ispreferably made of sheet metal suitably coated so as to resist' rust andcorrosion. Wooden members 23 are bolted tothe bottom of the shell andserve to support the upright members 10 which are secured thereto bymeans of angle brackets 24. v

The front of shell 22 is formed so as to be in contact with two sides ofmembers 10 and is secured thereto with the aid of a moulding 36.

Two or more brackets 25 are welded orotherwise secured to the inside ofthe back of shell 22 in such a position as to support the rear of theinner assembly.

The top and back of shell 22 are'removable so as to permit the innerassemblyto be put in place.

The'back is shown as being secured to the remainder" of the shell byscrews 37 which engage screw threads formed in angles 38 which arefastened, as by Welding, to the side members of the shell.' A similartype of construction may be used to secure the top to the main part ofshell 22.

The front of shell 22 is provided with a large upper opening andasmaller loweropening. The upper opening coincides with the open frontof liner 14 and is normally closed by a door 26. Door 26 comprisesarectangu- .lar frame 27, preferably of wood, to which issecured metalsheets 28 and 29. The space between sheets 28 and 29 is filled withinsulating material 15. A moulding 30 is placed around the innerperiphery of door 26 and serves to cover the edges of sheet 28. Theedges of sheet 29 are bent around the sides of frame 27 as is clearlyshown at 31. Door 26 is hung on a pair of hinges 32 and is held in itsclosed position by a latch 33. An additional strip of wood 36 ispreferably placed adjacent to frame 27 on the right hand side of thedoor as viewed in Fig. .3 in order to give additional support for thehinges.

The space within liner 14 may be termed a food storage compartment wh1lethe space in the lower part of shell 22 below the insulated liner may beaptly called the apparatus compartment. In the latter compartment ishoused the apparatus comprising a mechanical refrigerating unit, withthe exception of the evaporator which is placed in thefood storagecompartment. Access may be had to the apparatus compartment by means ofa removable panel 34 which is provided with louvres 35 to allowcirculation of air in case the refrigerating apparatus is of the aircooled type. Openings (not shown) are also provided in the back of theapparatus compartment to aid in the air circulation.

The preferred form of procedure in assembling the cabinet, made possibleby its Sim;- plified construction, is as follows:

The wood frame is first constructed by securing together members 10 and11 and 12. Liner 14 is then fastened to this frame. Next the cork board15, impregnated and coated with hydrolene, is put in place around theoutside of the liner and covered with water proof paper. Bands 18, 19and 20 are then placed around the now insulated liner and put undersuflicient tension to hold insulation 15 and the water proof paperfirmly in contact with the liner.

The inner assembly is now slipped into place within shell 22, the backand top of the latter not yet'having been placed thereon. Brackets 24are secured to members 10 and 23 and the front of shell 22 is fastenedto members 10 by mean-s of moulding 36. The

assembling of the refrigerator cabinet is now complete except forhangingdoor 26 and placing the back and top on shell 22.

The interior of the food storage compartment is provided with suitablesupports for shelves which have'not been shown as shelf arrangements areold and well known;

While I have shown and described a more or less specific form of myinvention, it is to be understood that modifications thereof fall withinits scope. For instance,'the bands need not be all parallel or at rightangles to each other but may pass around the insulated liner'in anydesired directions so as to secure the best binding of the, insulationto the liner, though the arrangement shown is preferred. It will beunderstood that the invention is to be limited only by the appendedclaims considered in connection with the prior art.
